Re: Best practice for getting a PCML file describing a given API?

This looks like a viable path - I'll look into it. Could you please elaborate on what you mean with "soft-coded offsets" - so that the programs know more than is present in the structure described in the header file, or calculated offsets based on that you know that on this position a type A is placed followed with a type B?


Many APIs have an output data structure with a fixed header section that has the offsets and lengths of the rest of the output structure. For example, the RTVM0300 structure in QMHRTVM has several offset and length subfields. The Reply Text is at offset QMHORT and has length QMHLRRTN00. You can express this in PCML like this
<data name="ReplyText" type="char"
offset="QMHORT" length="QMHLRRTN00" />

D QMHORT 53 56B 0
D* Offset Reply Text
D QMHLRRTN00 57 60B 0
